Fuel pump upgrade...

[Neinris]

I've been PMing Adam (06YarisRS) about some possible fuel upgrade options for the Yaris. He turboed his 2ZR, so I was wondering if he had upgraded his fuel pump, and was also wondering what he used if he did upgraded. Come to find out, he's also looking for a more robust fuel pump to replace his system.
Since I think my fuel pump is about due to be replaced, finding out from another 08 Yaris owner that I met at a car meet recently had to get his replaced, I thought I might as well look for something stronger since I plan on doing an engine swap later on.

In my search of DIYs in preparation for the fuel pump swap, I came across some interesting finds. I don't know when the change happened, but I believe that the fuel pump differ in the later models after 08. I'm using this link just as a visual representation of the earlier models fuel pump motor, I'm not advertising it's sale; https://www.amazon.com/Bernard-Bertha-23220-21131-23220-21132-23220-21210/dp/B07HQ4ZLR2

In this video that I found, the guys shows the difference in the pump motor housing between an 08 and a later model; https://www.youtube.com/watch?v=WBCXMP5vSW8&t=160s
At 1:34 he showed the two similar, but different housings. The later version has a longer neck at the bottom, and it uses a pump motor that's not straight through. At 2:40 he shows that you could purchase just the pump motor housing, but he said he doesn't recommend replacing just that. Seeing that you could replace just the pump motor housing sparked an idea in my mind. I will discuss in a bit.
In this thread, https://www.yarisworld.com/forums/showthread.php?t=38326 in post #4 by CTScott, he shows a different housing than the earlier models, and the pump is also different, refer to the visual aid linked above. This coincides with the video linked above. CTScott supposedly has/had an 09 Yaris, that's something to keep in mind.
I don't know if there's a fuel rating difference between the two pumps, but I think the latter is easier to upgrade.

The spark that I was talking about earlier is a fuel pump housing swap to make things simpler, which will explain my train of thoughts in the following discussion.
Digging further into things I've noticed that the supposedly 2013 RAV4 in this video uses the same basket size as the Yaris with the addition of an elbow at the bottom side; https://www.youtube.com/watch?v=cEIbRqdMyKk&t=189s
If I'm not mistaken, the 2013 RAV4 in America uses a 2AR-FE 2.5L I4 engine. What I can't seem to find is the fuel pump rating, and how is it compared to the later model Yaris, which seems to use the same pump motor. Are they in fact the same? Or does the RAV4 have more oomph?

My journey brings me deeper in the rabbit hole, when I came across the Venza's fuel pump, the Venza used the 1AR-FE 2.7L I4 or the 2GR-FE 3.5L V6 engines! The basket looks to be similar in size as the Yaris, but the pump motor housing is ginormous! Again, this is just for visual aid, not advertising sale; https://www.amazon.com/Fuel-Assembly-2009-2015-Toyota-Venza/dp/B07NQDSRKF
I know you're going to say, that basket is completely different. Ah! But remember, what I'm after is just the fuel pump motor housing swap. If you look closely, the fuel pump housing clips, which secures it in the basket, are on the same spots as the stock Yaris.
Ok, let's say the Venza fuel pump motor housing does fit, but how do you secure the hose to the Yaris' top canister? This part is what I'm not sure about neither. I believe that the hoses are heat shrunk to stay in place. I don't know if they can be heated up and be removed, then heated up again to secure them. I could buy a new hose; https://www.racetronix.biz/c/fuel-pump-installation-parts/fuel-feed-tubes-plastic/c649, but I don't know what the correct size is.

A distant option is the fuel pump from a Ford Taurus which also has a 3.5L V6. https://www.ebay.com/itm/Fuel-Pump-Assembly-For-Ford-Taurus-V6-3-5L-Lincoln-MKS-V6-3-7L-2011-2012-E2557M/253463997005
If you look closely, the securing clips also appears to lineup with the stock Yaris' basket.

I thought maybe I'd share this. I know the links that I sent are not of OEM parts, but like I said, all I'm after right now is the housing that would fit in the Yaris basket, and could buy an OEM or a known brand for that vehicle.

Share your thoughts.

This is great! I will be following this and contributing if I can. I think you are on to some great possibilities here. I don't know if I mentioned in our messaging that Rockauto lists the specs for most Delphi pumps per application. I could do a little legwork there for you if you want. Something that I did not mention - that my tuner did when I first had my car dyno tuned - is using a voltage booster to increase the stock pump capacity. We turned out not needing more fuel. Personally, I like your approach of upgrading pumps as I feel pushing the stock pump beyond it's normal duty cycle is less than desirable. I'd feel more comfortable with a higher capacity pump.

Toyota Yaris Fuel Pump Specs

Neinris, please let me know if you feel the info is pertinent. If not, I don't want to steer the thread off in a direction that you hadn't intended. I can remove or edit anything I post.

Note that the 2007 pump has an amp draw and 5.68A and a max pressure of 50 PSI. The 2009 pump has an amp draw of 10.68A and a max pressure of 100 PSI. The 2007 pump delivers 29 GPH and, oddly, the 2009 pump delivers 26 GPH. Since they are both Delphi pumps, I would expect the spec criteria would be the same. I am not sure if this actually means that the 2009 is a more robust pump capable of delivering more fuel at higher pressure. All pumps below run on a 44 PSI system pressure.

Here are the specs for a 2007 Delphi fuel pump:

Here are the specs for a 2009 Delphi fuel pump:

https://i.imgur.com/oy2cm2i.jpg


I wish there were specs on the pump body dimensions (diameter and length) published. The specs above are from RockAuto, but I also found data on the Delphi website:

Yes! These are very pertinent information. Thanks Adam! I guess normal operation they all pump at 44psi? The RAV4 is obviously the best pump of the three, it’s well rounded. I’m not even sure if going beyond that is even necessary. Thanks to your link I checked out the Venza’s fuel pumps, the 2.7L I4 and 3.5L V6 DO NOT share the same assembly. The info for the 2.7L (the one that I was going to experiment with) is incomplete, doesn’t mention the max pressure, but it says current draw average 10A, and average flow rating is 40gph. The RAV4 still beats it. And for the 3.5L V6, average current draw 8A, average flow rating 65gph, max pressure 80psi. It’s slight better than the RAV4, but the pump(motor) housing(canister) won’t work with the Yaris’ fuel pump assembly basket. So that’s out of the equation.
So, I believe that if you have the 09 Yaris fuel pump module assembly, you can drop in the RAV4 fuel pump motor. This is where the experiment starts. Maybe have the part store bring both motors out and compare dimensions. As far as filter, just used what’s made for that motor.

For the 08 and below, I don’t know what would be more cost effective, buying the 09 assembly and then getting the RAV4 motor, or just buy the RAV4 assembly and Frankenstein the basket with the top canister? But that involves having to unplug the hoses and swapping them. Not sure how to properly secure them afterwards???

Any more thoughts Adam? Thank you very much for your input. It narrowed down what I want to do.

Just did some more checking at rockauto. Both the 2007 and 2009 use the same whole assembly (ULTRA-POWER SP9031M). So, that's a bit confusing.

On another note, here is something interesting:

Using the Delphi link I provided above, I looked at pumps for the Corolla (a 2011). Interestingly, it lists 2 engines (1.8L and 2.4L). Both use the same pump (FGO938). So, it would seem that the pump is robust - certainly for the 1.8 application. Now, if one compares the specs of the Yaris and Corolla pumps, they're not terribly far off in specs. The 2009+ Yaris pump does seem to be more powerful that the 2009- pumps. But, the 2009- pumps state 29 GPH, whereas the 2009+ is 26 GPH. Maybe our stock pumps are strong enough for a turbo application. I am concerned a bit though, as CTScott mentioned 10 psi boost as about the max for the stock pump, and he was referring to the 2009+ pump, I assume. My tuner said my fueling was perfectly fine, but I'd rather not run my pump at the ragged edge. The above said, if all this pans out - aka the RAV4 pump will indeed fit in a 2009+ housing, that might be my best approach.

It's too bad that CaliYaris's post in the CTScott thread didn't still have the pics. He says that he installed a Walbro 255 with "minor modifications". Then Kou recommends the "190lph for the MR2 or corolla 255lph", stating that they should fit. All so confusing. lol

I wish I knew more about the pump specs. The GPH figure is probably free-flowing and, as such, may not be a valuable spec at all.

Anyway, Corolla pump spec:

I guess that there was a changed implemented in the later year of 09.
O'Reilly shows two different motors available for the 09: https://www.oreillyauto.com/shop/b/fuel---emissions-16775/fuel-pumps-tanks-16472/fuel-pump-strainer-16843/fuel-pump-12322/83db8e3f0135/2009/toyota/yaris
Don't know why they're so expensive though?
And RockAuto shows two different types of motors for the 09 as well: https://www.rockauto.com/en/catalog/toyota,2009,yaris,1.5l+l4,1443496,fuel+&+air,fuel+pump,6256
And only shows one type of motor for the 2010: https://www.rockauto.com/en/catalog/toyota,2010,yaris,1.5l+l4,1444575,fuel+&+air,fuel+pump,6256

I guess that might have solved that confusion.

It's interesting that you brought up the 2011 Corolla, I didn't even look into that. I just looked in RockAuto as to what it looks like, and it's the same as the 09- (I'm referring to the early 09 and below years):
https://www.rockauto.com/en/catalog/toyota,2011,corolla,1.8l+l4,1447615,fuel+&+air,fuel+pump,6256
So, is this the more viable route for the 09- Yaris?
And I guess it's the 2013 RAV4 for the 09+ Yaris?
Which one will you go for?

Still wondering if the RAV4's fuel pump motor will work in the 09+ Yaris?
Here's a picture from RockAuto, comparison of the 2010 Yaris fuel pump and 2013 RAV4 respectively:

[Neinris]

OK... WOW more confusion thrown into the mix. So apparently there are two different fuel pumps for the 2013 RAV4, the FWD and AWD. I just realized that the one that I've looking at to compare with the Yaris is the FWD pump, but the specification that has been discussed previously is from the AWD! The FWD specs from Delphi is incomplete, current draw is 10amp, doesn't say what the GPH, and max PSI. So right now, I don't know if the AWD pump motor will fit in the 09+ Yaris, but it seem that the FWD pump motor does, but still not confirmed.
I guess back on the drawing board for that one.

Did you see this thread? Kou looks like he just strapped a Walbro (EDIT: an AEM pump) into the lower assembly.

https://www.yarisworld.com/forums/showthread.php?t=52970&highlight=aftermarket+fuel+pump

I do wonder if just strapping on a fuel pump that's more powerful has other implications. It's a longshot, but I think I'll try messaging Kou.

OH WOW! What the heck is that a grenade? I definitely blows my thread away! :biggrin:

I like it, it gives everyone a really broad option.
I was just looking for a "drop in" replacement, but damn this took it overboard of what I was thinking. I guess I forgot to think outside the box. My cousin has a 255LPH pump laying around that he's not using. I didn't think about just strapping it with zip ties in the basket. I guess the thing that I was worried about was service support? Like if you have to replace the filter or something, could you go to the local auto part store if you need it right away? That might be trivial though.

On another note, I've done a visual comparison of the two RAV4 fuel pumps, FWD vs AWD. they appear to be identical, just one delivers more than the other, hence why it cost more.

Here's are the pictures courtesy of RockAuto FWD and AWD respectively:

I guess I didn't read his post thoroughly enough. It is a return style system. So, I think that would need a separate fuel pressure regulator, would it not? I know nothing about return vs returnless systems but will do some reading.

The above said, I like your ideas of installing a more serviceable setup.

Do you think you're going to try your cousins Walbro 255 in your car? I wonder if it could be used with the stock system - aka, returnless, or if, for that pump, you'd need a return style system.

EDIT: Check this out. It speaks of how the pump can overpower the stock FPR (on a Miata), causing the car to run rich. That wouldn't necessarily be a problem for me as I could pull fuel in the adversely affected portions of my map.

Thanks yet again Adam for sharing all those information and doing most of the research. More specifically about the fuel pressure regulator potential issue. But I don't think that's much of an issue, because with this non return style, the FPR that came along with the pump which is also in the basket. Or if you're going to drop in a different pump motor, ie. from a Corolla, then you should use the Corolla FPR. That should solve that problem.

I want to keep mine non return style, so I don't think I'll be strapping in the 255LPH motor that my cousin has laying around. I'm all about keeping this simple and making it user friendly for everyone.

I watched the MCM turboed Yaris again, and come to find out they kept the stock fuel pump!!! You can start at 13:00
https://www.youtube.com/watch?v=j6D9pB5Ig9Q

And they pushed their car to 200hp at the wheels, but broke the engine, I don't think from fuel issue, but mechanical, spun rod bearing if I remember correctly.

Some are probably asking, is it really worth going through all this hassle trying to figure out a fuel pump upgrade, when the stock one can handle up to 200hp, and maybe more? Most of us here in this community are not going to see 200hp at the wheels. But there are some out there that wants to push the envelope, and want to see what are the possibilities and other options.

In my opinion, if you want to push the limit of the engine in NA form, and want to upgrade your fuel pump motor, you can go with the 2011 Corolla pump motor and fuel pressure regulator. Apparently the 7th Gen Hilux also uses a similar motor, straight through type. That setup may very well be enough for 250hp, who knows.

The RAV4 route is what I'm probably going to experiment with, just for everyone entertainment. :laugh:

I don't know if I should buy a used one for now, I see some from eBay for less than $65 USD, and they show what the vehicle that they pulled it from, if in fact they pulled it from that vehicle, I wanted to make sure it's the AWD version. Or, should I get an aftermarket one, that's just as cheap, but I won't know if it's the AWD version, because all it says is the year it work in.

Any thoughts?

Check out post#23... I had forgotten all about this. It seems that an upgraded fuel pump can be used with a returnless system. A quote from that post:

" It wasn't that hard to convert the stock pump assembly to accept the Aeromotive Stealth 340 pump. I don't remember what I did exactly but I believe all I had to do was wire in the connector pigtail for the wiring connector, strap the pump to the 'frame' with some zip ties and maybe use a length of fuel hose. The 340 pump is actually quite compact for what it is."

And,

"Yes my Yaris is no longer a return style fuel system it is a dead-head."

First...I want to be sure that I'm not taking your thread in the wrong direction. Do you want this to be a general thread on fueling upgrades, or more of a focus on the specific upgrade you're planning. Just let me know, and I can become more focused. :thumbsup:

No, unfortunately. He sold that car and dropped off YW, afaik, before I got the pics. :frown:

Here's the specs of a pump from a 2008 (1ZZ-FE) Corolla. I think this would provide some extra fueling. It's really disappointing that these manufacturers don't list the pump body diameters.

https://i.imgur.com/T1VXKr7.jpg

Also, from additional reading, I don't think that a 1:1 FPR is necessary, as you suggested. I think we're barking up the right tree; upgrading the fuel pump only. I did email my tuner, so hopefully will hear back from him before too long.

EDIT: Just heard back from my tuner:

Here's my correspondence. (Will be updated as more responses come in):

Me: That's great, Brett. Thanks. I look forward to what you find out. I had another question about fueling. If I install a Walbro 190 or 155 pump, is there anything else I have to do to the system? It would require modifications to the basket, but I can do that. What I'm wondering about is do I need a different FPR? Will it throw my tune way off? I've read that guys have installed bigger fuel pumps in the Yaris and kept the returnless system. Others converted to a return system.

Brett (tuner): You should be fine with a fuel pump, I would suggest the 255hp, they are made to pop off at a higher pressure for boost application

Me: Great, thanks! What do you mean by "pop off"? Does that mean bypass at a certain pressure? I just figured that the best pump would be one that is the lowest output with headroom for my HP needs. The 255 is good for like up to 500+ HP. The 155 or 190 is good for up to 350+, I believe. What do you think of the Deatschwerks pumps or Aeromotive? And, no need for a 1:1 FPR or return style system, right?

Brett: Yes, many pumps will have a bypass at about 60-80psi, the 255hp pops at 110psi. I assume by 255hp, he means 255"lph".

Me: Thanks. So the stock pump in-tank regulator, which is 44 psi, would bypass at 44 psi, but I would get more volume of fuel delivery? There's no threat of overfueling with the upgraded pump?

Brett: You're close, the 44psi is your static regulated rail pressure, the pop off is there so the pump doesn't loose flow keeping up with regulated demand

Me: Perfect. So you don't see any problem with dropping in a bigger pump then? I have included a link, but I'd bet dollars to donuts you're already very familiar with this. You still think that the 255 is the way to go as opposed to the 190 or 155? I think either would provide more than enough fuel. I do wonder about my wiring as the stock pump draws around 6A. The 255 would be drawing around 9A (13.5V) at 44 psi, the 190 around 7A (13.5V) at 44 psi.

[Neinris]

I started this thread for everyone, it's not a build thread, so it's really free for all.

Remember the "High Flow Fuel" web site that I PMed you about? They show that the 2008 Corolla has the same motor can as to 09- Yaris.

https://www.highflowfuel.com/product-result/?ymmq=lk_automotive~yr_2008~mk_toyota~dq_corolla~z p_1-8l

And here's a pic from RockAuto:
61535

If those stats are correct, I might ditch the RAV4 conversion if that's the case.

The 2008 1ZZ Corolla draws less current than the RAV4, has better average flow than the -09 Yaris, and has a higher max PSI than the RAV4!
I think we have a winner!!!

I started this thread for everyone, it's not a build thread, so it's really free for all.

Remember the "High Flow Fuel" web site that I PMed you about? They show that the 2008 Corolla has the same motor can as to 09- Yaris.

https://www.highflowfuel.com/product-result/?ymmq=lk_automotive~yr_2008~mk_toyota~dq_corolla~z p_1-8l

And here's a pic from RockAuto:

If those stats are correct, I might ditch the RAV4 conversion if that's the case.

The 2008 1ZZ Corolla draws less current than the RAV4, has better average flow than the -09 Yaris, and has a higher max PSI than the RAV4!
I think we have a winner!!!

Sounds promising. Here is an application guide for the Beck Arnley pump (152-0989). Correct me if I'm wrong, but didn't the Corolla XRS come with the 2ZZ? If so, this pump must be quite strong.

I noticed that the Delphi pump for the same application seems physically longer than the Beck Arnley pump.

I noticed that as well about the Delphi pump. If you look at the picture again, it comes with a hose, spacers?, and clamps. I don't think it's a drop in replacement.

[Neinris]

Can the top in tank canister be cleaned out, say with water, or does it need to be replaced? Or is it fine to be reused and don't bother messing with it?

Not sure what you're referring to, man. Did you pull your pump?

[Neinris]

Not sure what you're referring to, man. Did you pull your pump?

Nope, I didn't pull it out yet. I don't have the torx nut driver to flip my rear seat up yet. I tried a 12 point nut driver, but it was slipping, I didn't want to further do any damage. And aside from the ghost ODB fault codes that I'm having, she's running pretty good right now. Perhaps in spring, after I get back from visiting my family at the end of the month.
Anyway, what I was referring to is the top canister which covers the top of the fuel tank. The one that the hoses and electrical connection hooks up to. I'm not really sure, but I think it's another evap canister? Not sure if those are good forever (for a long time anyway) or needs to be replaced? Or is it part of my issue right now? I'd sometimes see P043E, F, and P fault codes. I apologize I'm rolling into my other issues right now. :redface:

Adam, thanks for providing me this link I was able to do more research on my own:
https://partcat.com/delphi?_ga=2.17166009.1206759251.1615083772-2141033291.1615083772

I want to get everyone up to speed and reiterate the base line for the 09- and 09+ Yaris (as previously mention has different fuel pump motors and housings that resides in the basket), here's the most pertinent information according to Delphi's website:
09- Yaris
Avg amp draw: 5
Avg flow rating: 29gph (multiply 3.7854118 for LPH conversion)
Max PSI: 50

09+ Yaris
Avg amp draw: 10
Avg flow rating 26gph
Max PSI: 100

In my research, I want to make correction to the information that was previously provided about the 2008 Corolla fuel pump. There's a product info provided in the site that's confusing. If you select electric fuel pump, it shows an image of a motor with a longer can, which won't be a direct drop in for any of the Yaris. Here's the specs:
Avg amp draw: 5
Avg flow rating: 33gph
Max PSI: 106

But if you select "Fuel Pump and Strainer Set", which is the direct drop in swap, the following specs is given:
Avg amp draw: 6
Avg flow rating: 26gph
Max PSI: 65

So this is debatable as far as considering it as an upgrade if you compare it to the 09- Yaris' stats. I think the 09- Yaris wins this fight, not only is it drawing less amp, but also delivering more gph regardless of the max psi it produces.

In my search for an alternative drop in upgrade for the 09- Yaris, I found that the 08 RAV4 has the same motor design. It has the following specs:
Avg amp draw: 10
Avg flow rating: 30gph
Max PSI: 120

For the 1gph gained, I don't think doubling the amp draw is justifiable, although the max psi will be more than doubled. Comparing it to the 09+ pump on the other hand it wins on all accounts. With all that said, I am still considering it as a possible upgrade for the 09- Yaris.

I've checked the other vehicles with the same motor can design, Avalon, Camry, Solara, frankly the RAV4 beats all of them and the 09- Yaris is actually better.

For the 09+ Yaris, a possible drop in option would also come for the RAV4, but the 2013 generation non-Japan built. It has the following specs:
Avg amp draw: 10
Avg flow rating: 38gph
Max PSI: 123

It beats the 09+ stats in all accounts, the only thing is it's not guaranteed that it will fit, the pictures shows that they are very similar, I'm just now sure as far as the dimensions yet. If anyone is wondering what pictures I use to compare, I used the pictures provided by www.RockAuto.com. If you're curious as well, you can do your own research.

I'm still leaning towards the 2013 RAV4 fuel pump, to justify the more amp draw, but it will require purchasing the 09+ fuel pump housing.
I hope you all stay tuned! :redface:

I completely forgot about this thread...

Picture that CTScott posted shows that the 09+ Yaris has a completely different top than the 09-, see comparison below:

09-

09+

Not sure if 09+ have a "returned" system, but that top hose coupling sure looks big. And the 09+ got rid of the top canister.

09-

09+

I'm making myself dizzy... :laugh:

[06YarisRS]

Yeah, I'm really interested in why Toyota changed the system in 2009. You're not the only one getting dizzy. Haha. As mentioned in my PM to you, I'm hoping to speak with Delphi tomorrow to see if they can provide dimensional specs (diameter and length) on their various pump bodies. Do you think it makes sense to do this first - aka see if they have a pump that will physically fit, then worry about the connections? Maybe I should inquire about 2009- pumps first? Open to thoughts and suggestions.

I do apologize as I have been a bit focused on my engine management at the moment. I was speaking with FTG Tuning and they think they may be able to write to my stock ECU fueling maps, thus allowing me to eliminate the need for my piggyback. My tuner is also pursuing this avenue.

[Neinris]

I found this from RockAuto:

https://www.rockauto.com/en/moreinfo.php?pk=8819376&cc=1441511&jsn=905&jsn=905

It's a pump motor for a 2008 RAV4 that has a similar if not the same design as the 09- Yaris. The company claims the following specs below and supposedly draw less current:


Inlet Type Strainer
Internal or External Internal
Maximum Free Flow (GPH) 55.0
Maximum Pump Pressure (PSI) 85.0
Minimum Free Flow (GPH) 45.0
Minimum Pump Pressure (PSI) 75.0
Outlet Size (in) 5/16
Outlet Type Recessed Quick Connect
Package Contents Pump & Kit
Pump Type Turbine

If it's in fact putting out 45GPH minimum, that's 170LPH and max of 208LPH. :eyebulge:
Forget the 255LPH if it's not a drop in.

Adam, I need to apologize if I’m pestering you, I just got all excited with all the findings, and I want to make sure we’re putting out accurate information.
We all have our own issues that we need to deal with. I’m still dealing with my ghost fault codes, no CEL, bad evap canister pump, and pursuing an alternative rear disc conversion, but those are all on another thread. :redface:

Like I mentioned earlier in the thread, I’m after more of a drop in upgrade. I’m gearing towards readily serviceability, not to say a 255lph pump is not easily serviceable. I’m just not sure how it will work without of the fuel regulator. Is it all going to just depend on the injectors to control the amount of fuel? Maybe the ECU will control the A/F mixture on its own? I’m still learning how it all works. :biggrin:
If someone has strapped in a 255lph pump please share.

Man, you're not pestering me! I'm excited about this too, and like you, I think, finding it a little confusing given the wide variety of information and pump specs out there. I would also prefer a drop-in solution. Given that my AFRs are not bad now, and I'm not planning to significantly increase power, I don't need anything as hefty as a 255 or 340 lph pump. I'd just like a little headroom and run knowing that I'm not close to maxing out my system. I'd like to pursue finding out if a 2009+ fuel pump assembly can go into my 2006. I keep thinking about the RAV4 pump as well. I think this is a very worthwhile pursuit. :thumbsup: And, of course, each of us will be focusing on other aspects of our cars as we go. I'm also focused on the possibility of tuning my stock ECU for boost. :burnrubber:

[Neinris]

So what's the point of increasing your fuel pump's delivery if your fuel pressure regulator (FPR) can't keep up with the supply?

In an old post, there was research made that stated that the OEM FPR is rated for 44.1 to 49.7 psi:
https://www.yarisworld.com/forums/showthread.php?t=15442

I wonder where he got that info from? I want to find out what's the range for the other FPR that I'm going to mention below.
According to RockAuto, the Delphi Yaris' FPR is rated for 44 psi, must be the base.
https://www.rockauto.com/en/moreinfo.php?pk=10910972&cc=1441505&jsn=1686

I was curious as to what other FPR would work as a drop in upgrade. And I came across with I believe the 05-08 IS350, and it's FPR looks to fit in the Yaris, and it's base pressure is 51 psi.
https://www.rockauto.com/en/moreinfo.php?pk=10910820&cc=1434544&jsn=1492&jsn=1492

Coincidentally, there are two 07 IS350 at LKQ pick and pull near me, so I'll be grabbing that FPR, and test fitting it in my Dee Dee.

I guess you could just remove the FPR, and install an inline FPR and even have a gauge. But I'm not comfortable with my installation ability, I don't want fuel spraying in my engine bay.

[Neinris]

Did some more research, found out that RockAuto.com lists the same fuel filter for the 3rd GEN RAV4 (06-12) 2.4L I4 engine and 09- Yaris.

https://www.rockauto.com/en/moreinfo.php?pk=1998768&cc=1441511&jsn=837

This means that the fuel pump for the RAV4 will drop in into a 09- Yaris.

The pump motor that I'm specifically looking at dropping in is this:

https://www.rockauto.com/en/moreinfo.php?pk=8819376&cc=1441511&jsn=841

The manufacturer claims the following specs:

Maximum Free Flow (GPH) 55.0
Maximum Pump Pressure (PSI) 85.0
Minimum Free Flow (GPH) 45.0
Minimum Pump Pressure (PSI) 75.0

I'll be combining this pump with the 9th GEN and up Corolla fuel pressure regulator (FPR). The Delphi FPR show that theirs has a base psi of 46, compare to their FPR for the Yaris 44 psi:
https://www.rockauto.com/en/moreinfo.php?pk=10910568&cc=1433059&jsn=995

If you're boosting your engine, and staying with the returnless fuel system, you might want to use the FPR from the 2005-13 IS350, it's has a base of 51 psi.
https://www.rockauto.com/en/moreinfo.php?pk=10910820&cc=1505190&jsn=1630

Disclaimer, I don't know if the OEM (DENSO) has the same through put as Delphi, it might be lower, or it might be the same. The one I'm dropping in my car is the FPR from a 2015 Corolla (DENSO) that I grabbed from the junkyard. Background if you haven't been following this, I'm changing the fuel pump motor for my 08 Yaris, since I'll be driving her back to Maryland when I move back in June. A fellow 08 Yaris owner had to replace his a month or so ago, so I think I'm about due for a replacement. I don't want any issue on my trip back to MD, so I'm getting ahead of it, that's also why I'm trying to fix every little issue I have with her, if you're following my other thread. Also, plan on doing an engine swap in the future. So I thought I might as well upgrade my fuel delivery system.

Anyway, for you 09+ Yaris owners, don't fret, I'm researching a drop in pump motor for you guys if you so desire to do an upgrade. But looking at again from a RAV4, 4th GEN 2013-18, it looks like that pump motor fits in your fuel filter/pump motor housing. It has more GPH/LPH and has a higher psi overhead. Unfortunately there's on 09+ Yaris and 4th gen RAV4 in the junkyard near me, so I can't just grab their pump motor to do a physical comparison.

I believe you guys have a returned system, can someone please verify.

Of course what I'm presenting here are just drop in options, there's nothing stopping you from strapping a pump motor, say a 255LPH, and installing an inline FPR. Which would probably be cheaper compare to buying Delphi products, and if there's no junkyard near you to pull parts from. The inline FPR could also have dual function if you install the one with a gauge.

Kudos for the excellent work! This is such great news. I still plan to pull my pump soon to have a look at it. I'm pumped (bad pun, I know) to drop this upgraded pump and fuel regulator in and see how it changes my fueling. I expect that the 46 psi system pressure FPR will be ample, but there's always the IS350 FPR if I need a bit more fuel. Again, stellar work! :thumbsup:

Sorry to bring back an old thread but I looked into this and looks like the 07-23 CBR600RR and 07-18 CBR1000RR fuel pump are of the same dimension.
